Mathematics
1 answer:
lesantik [10]3 years ago
6 0

1. 1, 2, 3 has 3! = 6 possible permutations:

1 2 3 // 1 3 2 // 2 1 3 // 2 3 1 // 3 1 2 // 3 2 1

2. T, V, W taken 2 at a time has \dfrac{3!}{(3-2)!}=6 possible permutations:

T V // T W // V T // V W // W T // W V

3. I'll replace these symbols with f, s, h, and t (face, sun, heart, triangle). This sequence has \dfrac{4!}{(4-2)!}=12 possible permutations:

f s // f h // f t // s f // s h // s t // h f // h s // h t // t f // t s // t h

4. This has 4! = 24 possible permutations.

A B C D // A B D C // A C B D // A C D B // A D B C // A D C B //

B A C D // B A D C // B C A D // B C D A // B D A C // B D C A //

C A B D // C A D B // C B A D // C B D A // C D A B // C D B A //

D A B C // D A C B // D B A C // D B C A // D C A B // D C B A

Carmen is considering joining one of the two movie clubs. Movie Galore charges a monthly membership fee of $10, plus $0.50 per m
lakkis [162]
25 movies.

So basically you start and end at 1 month so,

Galore Cost = 
$10
Galore Per Movie = 
0.5 x 25 = 12.5 + 10 = $22,5

Cinephile Cost = 
$15
Cinephile Per Movie = 
0.25 x 25 = 6.25 + 15 = 21.25

These questions are just trial and error

which of the following expresses the coordinates of the foci of the conic section shown below? (x-2)^2/4+(y+5)^2/9
elena55 [62]

Step-by-step explanation:

\frac{(x - 2) {}^{2} }{4}  +  \frac{(y + 5) {}^{2} }{9}  = 1

This is the equation of the ellipse. Since the denominator is greater for the y values, we have a vertical ellipse. Remember a>b, so a

The formula for the foci of the vertical ellipse is

(h,k+c) and (h,k-c).

where c is

Our center (h,k) is (2, -5)

{c}^{2}  =  {a}^{2}  -  {b}^{2}

Here a^2 is 9, b^2 is 4.

{c}^{2}  = 9 - 4

{c}^{2}  = 5

c =  \sqrt{5}

So our foci is

(2, - 5 +  \sqrt{5} )

and

(2, - 5 -  \sqrt{5} )
